Needed: Circuit for Signal Generator 75W Oscillates at 100Ghz-200Ghz

[sciexp]

I am devising an experiment that requires a 75W signal generator in the 100GHz-200GHz range. I am interested in the resonance effects in this region. Could someone please advise me on the circuit design and materials required for shielding for such a signal generator and related safety issues for this design construction. Thanks...

Google 'Active Denial System' for an example of 94 GHz in action.

That's alot of power. Solid state can't get close to that. That can only be a very expensive TWT amplifier or group of TWT's combined with a waveguide power combiner.

Guessing $lots of money.

Here's one reference.
The goal of this program was a TWT (double comb delay line structure) in the 94-GHz frequency range with an instantaneous bandwidth greater than 500 MHz (tunable within 1 GHz) and an output peak power greater than 200 W in the center of the band (150 W over the band) for a duty cycle of max.
